An additive manufacturing apparatus includes a first vertically-extending support leg, a second vertically-extending support leg, and a gantry supported on the first and second support legs. The additive manufacturing apparatus also includes a work table movably supported beneath the gantry, a print head supported on the gantry, and a trim head supported on the gantry with the print head.

Certain aspects and features relate to using an image modifier to generate digital designs and to printing the digital designs on a structure for flooring or other decoration that can more realistically mimic designs found in nature or otherwise provide designers with the freedom to create aesthetic designs more easily. An image modifier can receive an image, such as an image of a naturally occurring view and generate modified designs based on the image. The modified designs can be slight modifications to the image and printed on the structures for flooring such that together the printed structures exhibit the appearance of a design found in nature or a desired appearance by a designer.

A method and system of additively-manufacturing a structure having a reinforced access opening includes printing, via an additive printing device having at least one printer head, a portion of the structure adjacent to a support surface. The portion of the structure is printed of a cementitious material, and the printed portion of the structure defines an access opening for the structure. Moreover, the method includes providing a void of the cementitious material at a top boundary of the access opening, placing one or more reinforcement members in the void such that the one or more reinforcement members extend across the void, and continuing to print the printed portion of the structure around the void to build up the structure. Thus, the method also includes backfilling the void with a backfill material to incorporate the one or more reinforcement members within the void into the printed portion of the structure.

A system and method for manufacturing composite parts has been developed which offers the ability to produce composite parts in an infusion resin process without the use of expensive preforms or tools. In addition, the methods of manufacturing composite parts described herein offer the ability to produce composite parts having complex structures without the need for complex tooling. The method of manufacturing and systems described herein typically include printing a part skeleton using an additive manufacturing process followed by infusing the part skeleton with resin and curing the resin infused part skeleton to form the composite part.
